Babcock and Wilcox Steam Generator, Patent Model

Description
This model was submitted to the U.S. Patent Office with the application for the patent issued to George H. Babcock, of Plainfield, Hew Jersey, and Stephen Wilcox, of Brooklyn, New York, April 4, 1876, no. 175548.
The model represents the typical elements of an inclined tube, horizontal longitudinal drum boiler upon which are shown the mode of mounting and supporting such boilers and the provisions for making the connections of the parts that are the subject of the patent.
The drum of the boiler is represented as having cast-iron ends, each of which is formed with a stout horn near the top adapted to receive a suspension link from a cross girder resting upon columns at the sides of the boiler. Each end casting is further provided with a series of holes near the bottom properly adapted to receive tubes joined thereto by the process known as expanding. These tubes are joined at the front and back to the vertical tubes rising from the water-tube headers by means of hollow castings in which hand holes are provided that permit both sets of tubes to be expanded in the openings in the castings.
These improvements are said to be the results of the inventors’ experience with the boiler patented by them February 18, 1873, no. 135877.
